FIG. 2. Showing a sketch of the proper construction of a gutter in a dairy barn which 

 will remove the liquid manure. This gutter should be twenty-seven inches wide. The bottom 

 should be inclined one-half inch to the foot. The spaces between the outlets may range from 

 twelve to fifteen feet. The depth of the gutter on the cow's side should be at least one foot. 

 The advantage of this gutter over a narrow trough or half circle is as follows: 



It has been the experience with dairymen having square, narrow gutters back of cows 

 that the solid manure blocks the flow of the liquid manure. Hence it is necessary to remove 

 by hand both the liquid and the solid manure. With the scheme as shown above the gutter is 

 wide and the solid manure is voided on the side of the gutter on which the cow stands. The 

 gutter bein^ wide, the solid manure does not cover the bottom of the gutter, thus allowing 

 the liquid manure to flow on the lowest end of the gutter, and from there to the sewage dis- 

 posal system.
